MODELING OF FIBER ORIENTATION IN FIBER-REINFORCED FRESH CONCRETE FLOW

Popis výsledku v původním jazyce

In recent years, popularity of unconventional reinforcing of concrete is growing. Especially fiber reinforcement has very wide usage in high performance concretes like Self Compacting Concrete (SCC). Designing of structures made of fiber-reinforced concrete assumes uniform distribution of the fibers through the structure. Violating this assumption can lead to over-estimated design and poten- tially to collapse of the structure. Therefore, tools for the prediction of the distri- bution and orientation ofthe fibers in the specimen are needed. This paper deals with developing and implementing suitable tool for prediction of the orientation of fibers in a fluid based on the knowledge of the velocity field. Statistical approach to the topic is employed, where orientation of a fiber is described by a probability distribution of the fiber angle.
